Description

Technical Field

[0001] This utility model relates to the field of pattern sewing machine technology, specifically to a feeding device for a pattern sewing machine. Background Technology

[0002] Pattern making machines are widely used for sewing patterns on various handbags, garments, textiles, leather goods, luggage, shoes, sofas, sports and recreational equipment, etc. Using pattern making machines can increase production volume, improve production efficiency, and enhance production precision.

[0003] In the automated production process of pattern sewing fabric, the fabric needs to be stacked to improve space utilization. During sewing, the stacked fabric is taken out one by one, and after sewing is completed, the patterned fabric is stacked and stored one by one. These are all important parts of the entire sewing production process.

[0004] The problem with existing technologies is that they still rely on manual stacking, which reduces production efficiency. Therefore, utilizing automated equipment to assist in feeding and stacking will significantly improve the production efficiency of pattern making machines. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned technology, this utility model provides a feeding device for a pattern making machine.

[0006] The technical solution of this utility model is as follows: A feeding device for a pattern making machine, the device comprising a frame, a robotic arm, a lifting platform, and an infeed conveyor belt or an outfeed conveyor belt. The robotic arm includes a suction cup gripper, a vacuum generator, a vacuum pipeline, and a controller. The suction cup gripper has several vacuum suction cups corresponding to the fabric outline. The vacuum generator is connected to each vacuum suction cup through the vacuum pipeline. The vacuum suction cups adsorb the fabric onto the lifting platform, the infeed conveyor belt, or the outfeed conveyor belt. The lifting platform includes a vertical track, a lifting seat, and a drive mechanism. The lifting seat slides along the vertical track and is linked with the drive mechanism. The lifting seat has a support platform in the horizontal direction. The drive mechanism is signal-linked with the controller, driving the lifting seat to gradually rise or fall with the number of times the robotic arm handles the fabric.

[0007] Further features of this invention: The drive mechanism includes a toothed belt, a driven pulley, a wheel seat, a drive pulley, and a drive motor. The frame is provided with mounting beams vertically above and below the lifting stroke of the lifting platform. The drive motor and the wheel seat are fixedly mounted on the mounting beams on the upper and lower sides, respectively. The drive pulley rotates synchronously with the output shaft of the drive motor, and the driven pulley rotates in conjunction with the wheel seat. The two ends of the toothed belt are respectively sleeved on the drive pulley and the driven pulley for meshing. The middle section of the belt is fixedly connected to the lifting seat. The drive motor rotates forward and backward to drive the lifting seat to move up and down.

[0008] Using the above technical solution, the position of the drive motor and wheel seat makes the toothed belt rotate in an elongated oval shape, and its straight part is fixedly connected to the lifting seat. The forward and reverse rotation pulls the lifting seat to slide up and down along the vertical track.

[0009] Further features of this invention: The robotic arm also includes a crossbeam and a pair of drive cylinders. The crossbeam is arranged parallel to the feeding conveyor belt or the discharging conveyor belt. The pair of drive cylinders are located at both ends of the crossbeam. The pair of drive cylinders are detachably fixed to the frame and are arranged at an angle. The piston rods of the pair of drive cylinders are detachably connected to the two ends of the crossbeam respectively. The suction cup gripper is located on the crossbeam, and the vacuum suction cup faces the feeding conveyor belt or the discharging conveyor belt. The pair of drive cylinders are linked with the controller and the drive mechanism to drive the crossbeam to reciprocate between the lifting platform and the feeding conveyor belt or the discharging conveyor belt.

[0010] Using the above technical solution, the extension and retraction of the drive cylinder moves the crossbeam closer to the feeding conveyor belt. The vacuum suction cup adsorbs the fabric on the conveyor belt, and then the crossbeam carries the fabric to the vertical position above the lifting platform. The adsorption is then released, and the fabric falls onto the lifting platform. The reverse is also true.

[0011] Further features of this utility model: The frame is assembled from aluminum profiles. The frame includes a horizontal adjustment part and a cylinder seat. The horizontal adjustment part is horizontally arranged between the lifting platform and the feeding conveyor belt and the discharging conveyor belt. The cylinder seat and the profile groove of the horizontal adjustment part are detachably fixedly connected by fastening. Using the above technical solution, the cylinder block can adjust its position according to the working conditions.

[0012] The cylinder seat is hinged to the drive cylinder seat. The cylinder seat is provided with several angle holes and a limiting pin around the hinge. The limiting pin locks the rotation angle of the drive cylinder relative to the cylinder seat.

[0013] By adopting the above technical solution, the tilt angle of the drive cylinder is adjusted according to the working conditions to adjust the direction of the crossbeam movement.

[0014] A further feature of this invention is that a number of lifting platforms are provided on the frame along the direction of travel of the feeding or discharging conveyor belt, and a number of suction cup claws are provided on the crossbeam corresponding to the number and position of the lifting platforms.

[0015] A further feature of this invention is that a servo motor and a rotary table are mounted on the cylinder base, the drive cylinder is fixed on the rotary table, the servo motor is fixedly connected to the cylinder base and rotates coaxially with the rotary table to control the rotation angle of the drive cylinder.

[0016] The beneficial effects of this utility model are as follows: This application utilizes the linkage between the lifting platform, vacuum suction cup, and drive cylinder. Each time the suction cup's picking claw picks up material, the crossbeam performs a reciprocating motion, causing the fabric to be sucked onto the lifting platform and lowered. Simultaneously, the lifting platform lowers in coordination according to the number of picking operations and the preset stacking thickness, ensuring that the top of the stacked fabric aligns with the suction cup's picking claw, preventing the stack from tilting due to changes in distance during the lowering process. This feeding device assists in the gradual stacking or removal of fabric in the pattern making machine, improving the efficiency of automated production. Attached Figure Description

The robotic arm 2 includes a suction cup gripper 21, a vacuum generator, a vacuum pipeline, and a controller. The suction cup gripper 21 has several vacuum suction cups 22 arranged on it corresponding to the fabric outline. The vacuum generator is connected to each vacuum suction cup 22 through the vacuum pipeline. The vacuum suction cups 22 adsorb the fabric onto the lifting platform 3, the infeed conveyor belt, or the outfeed conveyor belt. The lifting platform 3 includes a vertical track 31, a lifting seat 32, and a drive mechanism. The lifting seat 32 slides along the vertical track 31 and is linked with the drive mechanism. The lifting seat 32 has a support platform 33 arranged horizontally. The drive mechanism is linked with the controller signal to drive the lifting seat 32 to gradually rise or fall as the robotic arm 2 moves the fabric.

[0026] The drive mechanism includes a toothed belt 34, a driven pulley 35, a wheel seat 36, a drive pulley 37, and a drive motor 38. The frame 1 has mounting beams vertically above and below the lifting stroke of the lifting platform 3. The drive motor 38 and the wheel seat 36 are fixedly mounted on the mounting beams on the upper and lower sides, respectively. The drive pulley 37 rotates synchronously with the output shaft of the drive motor 38. The driven pulley 35 rotates with the wheel seat 36. The two ends of the toothed belt 34 are respectively sleeved on the drive pulley 37 and the driven pulley 35 and mesh with them. The middle section of the belt is fixedly connected to the lifting seat 32. The drive motor 38 drives the lifting seat 32 to move up and down by rotating in both directions.

[0027] The positions of the drive motor 38 and the wheel seat 36 cause the toothed belt 34 to rotate in an elongated oval shape. Its straight part is fixedly connected to the lifting seat 32, and the forward and reverse rotation pulls the lifting seat 32 to slide up and down along the vertical track 31.

[0028] The robotic arm 2 also includes a crossbeam 23 and a pair of drive cylinders 24. The crossbeam 23 is arranged parallel to the feeding conveyor belt or the discharging conveyor belt. The pair of drive cylinders 24 are located at both ends of the crossbeam 23. The pair of drive cylinders 24 are detachably fixedly connected to the frame 1 and are arranged at an angle. The piston rods of the pair of drive cylinders 24 are detachably connected to the two ends of the crossbeam 23 respectively. The suction cup claw 21 is located on the crossbeam 23, and the vacuum suction cup 22 faces the feeding conveyor belt or the discharging conveyor belt. The pair of drive cylinders 24 are linked with the controller and the drive mechanism to drive the crossbeam 23 to reciprocate between the lifting platform 3 and the feeding conveyor belt or the discharging conveyor belt.

[0029] The extension and retraction of the drive cylinder 24 causes the crossbeam 23 to approach the feeding conveyor belt. The vacuum suction cup 22 adsorbs the fabric on the conveyor belt, and then the crossbeam 23 carries the fabric to the vertical position above the lifting platform 3. The adsorption is then released, and the fabric falls onto the lifting platform 3. The reverse is also true.

[0030] The frame 1 is assembled from aluminum profiles. The frame 1 includes a horizontal adjustment part and a cylinder seat 25. The horizontal adjustment part is horizontally arranged between the lifting platform 3 and the feeding conveyor belt and the discharging conveyor belt. The cylinder seat 25 is detachably fixed to the profile groove of the horizontal adjustment part by fastening. The cylinder seat 25 can adjust its position according to the operating conditions.

[0031] The cylinder seat 25 is hinged to the drive cylinder 24 seat. The cylinder seat 25 is provided with a number of angle holes 251 and a limiting pin around the hinge. The limiting pin locks the rotation angle of the drive cylinder 24 relative to the cylinder seat 25.

[0032] Adjust the tilt angle of the drive cylinder 24 according to the working conditions to adjust the direction of movement of the crossbeam 23.

[0033] The frame 1 is provided with several sets of lifting platforms 3 along the direction of travel of the feeding conveyor belt or the discharging conveyor belt, and the crossbeam 23 is provided with several suction cup claws 21 corresponding to the number and position of the several sets of lifting platforms 3.

[0035] This application utilizes the coordinated operation of a lifting platform 3, a vacuum suction cup 22, and a drive cylinder 24. Each time the suction cup's picking claw 21 picks up material, the crossbeam 23 performs a reciprocating motion, causing the fabric to be sucked up and lowered onto the lifting platform 3. Simultaneously, the lifting platform 3 lowers in tandem according to the number of picks and the preset stacking thickness, ensuring that the top of the stacked fabric aligns with the suction cup's picking claw 21, preventing the stack from tilting due to changes in distance during the lowering process. This feeding device assists in the gradual stacking or removal of fabric from the pattern-making machine, improving automated production efficiency.
